What Cross-perspective Topic Modeling can do for you

  • Experiment with different settings

  • Downloading and preprocessing of the Dutch parliamentary proceedings

cptm is an implementation of cross-perspective topic modeling, which is is a topic modeling method that simultaneously extract topics and opinions from text. Topics are learned from nouns and opinions from adjectives. To use this tool, you need a corpus that is divided into perspectives. In the DiLiPaD project a perspective refers to a political party. We used this tool to extract topics and opinions from parliamentary proceedings.
